THE number of days work lost due to industrial disputes more than doubled last year.
Workers missed 8,486 days because of rows with their employers, compared with 3,695 days the previous year.
However, there were just five industrial disputes last year and eight in 2011.
Two disputes at Bord na Mona and Irish Cement accounted for almost three-quarters of the days lost last year. The disputes accounted for 6,114 of the 8,486 days lost.
Irish Cement closed for a total of 46 days, leading to over 3,600 lost days, while there was a three-day strike at Bord na Mona. The dispute at CRH subsidiary Irish Cement involved 110 workers.
They went on strike at plants in Limerick and Meath after claiming they were owed between €5,500 and €9,500 each in pay increments.
The staff claimed the company would only pay the money if they accepted a pay cut of up to 18pc. The seven-week strike was called off after workers accepted proposals to end the dispute last May.
The other three disputes that led to work stoppages last year were at the Eddie Stobart haulage company, Musgraves in Cork, and a strike by taxi drivers at Dublin Airport.
However, there were no days lost due to industrial disputes during the final three months of last year.
